To all whom it may concern:

Be it known that l, FRANK G. HARRISON, alcitizen of the United States, residing at Massillon, in the county of Stark-and State of Ohio, have invented certain new and useful Improvements in Fodder-Cutters, of which the following is a specification.

The invention relates to improvements in fodder cutters and particularly to that class of cutters in which there is mounted in front of a pair of feeding rollsan.

.a stationary cutting bar a cutting cylinder comprising a series of spirally arranged arms carrying knives or cut ters adapted to cut and disentegrate the material as it is fed over and in front of said stationary cutting bar.

The general object of the invention is to produce a generally imprdved device of this class in compact form adapted to insure a proper feeding and the ready and quick discharge of the cut and discntegrated material as received from the cutting cylinder.

In carrying out this object, I provide a pneumatic blower or fan mounted transversely in front of, and below the cutting-cylinder, and provided at its rear with a chute adapted to receive the cut and disintegrated material and convey the same to the blower or fan whereby the same is discharged.

Another purpose of the invention isto provide a with the machine, proper.

Further objects and advantages of the invention will appear from the following description taken in connection with the accompanying drawings forming a part of this specification. I

Referring now to the drawings, Figure l is a vertical sectional view of the improved cutter; Fig. 2, a plan view of the same; Fig. 3, a left side view of the same,

partly in section; Fig. 4, a right side view of the same, partly in section; .Fig. 5, a sectional view of the fan or blower taken through line 55, -oi Fig. 1 Fig. 6, aright side view of the feeding-trough showing its mode of attachment to the machine; Fig. 7, a detailed perspective view of one of the swiveled compression-arms of one of the feeding-cylinders; Fig. 8, .a side view of the same, partly in section; Fig. 9, a detail view of the depending bracket, attached to upper side arms of frame of machine and adapted to carry one end of the driving shaft of the fan or blower; Fig. 10, aperspeetive view of 'the Operating lever for throwing feed mechanism into and out of operation; Fig. ll, a side view of the same showing its connections with the movable bearing attached to one ofthe upper side arms of'frame of machine; and Fig. 12, a detached perspective view of one offan-blades and its attached angle bar;

Similar numerals of reference. indicate like parts throughout all thefigurcs of the drawings.

nates the lower sidearms of same, supported upon the base beams 3 and connected to said upper side arms 1, by means of brace-arms 4, secured thereto in any suitable and convenient manner. The blower-caseS incloses the Karl and is mounted transversely upon the lower side arms2, in any suitable and convenient manner, and is provided at its side with an upwardly-extending discharge-pipe 6. A bearing 7,, 'iof'the fan-shaft, is mounted within an opening 8, formed in the side of the blowercase 5', and is secured to said blower-case 5, by means of a series of bolts 8, pasing through openings formed about the periphery of saidopening 8. second bearing 9, is formed upon the depending bracket 10; and which bracket has its ends secured beneath the upper side arms 1, hereinbefore referred to, said'ends being provided with the flanges or guides 11; The drivingshaft 12 of the fan or blower is mounted longitudinally of the machine'in the bearings 7, and 9, and carries upon one end a driven-pulley l3, and upon the other a bevel-gear 14. The fan-disk 15, is mounted and secured to the driving-shaft 12, in any suitable and convenient manner and carries a series of supporting-anglearms16, secured to the fan-disk 15, by means of bol ts117 and is further supported by means of lugs 18, formed integral with the fan disk 15. 1

A series of paddle blades or fans 19,are secured to the supporting-angle-arrns 1 6 in any suitable and convenient manner, but disposed rearwardly at an angle to a line drawn at right angles to the line of rotation of the fan. This isa very important part and principle in the construction of fans or blowersiof this class, as 1 it has been found in practice that where the fans orpaddles are radially disposed in the usual manner, at right angles to the line 'oi= travel in rotating, there is a tendency to' carry the material past the upwardly-extending discharge-pipe 6, whereby the material is carried about with the tan, lclogging the same, and

preventing the same from performing its proper iunction. This tendencyis not so evidentwhere the discharge-pipe is at the lower portion of the-blower-case and when the discharge-pipe does not extend up wardly, as in these instances the force of gravity does not so strongly oppose the centrifugal force caused by the rotation of the fan.

Where the discharge pipe is disposed as herein shown and described,l accelerate the centrifugal force by disposing the blades or fans 19 as herein shown and described.

i The usual stationary cutting bar 20, is disposed transvcrsely in front of the feed-rolls 21, and 21, and near the periphery of the cuttingcylinder 22. Near the presenting a shear-edge adjacent to the' periphery of the cutting-eylindergg with the cutting-bur and pre with eyes 55, odapzed to rocei.
